The series qual for FO's was hitting the street right as I was in my last six months in the Fleet, and the biggest heartburn we-all had with it was having to learn the G2/Grim Reaper scope stuff. My RAG class was the first to do the G2-HE2K split up front, as opposed to a differences class post-stan check, so by the time this came around, none of the JO's in my squadron had so much as seen a CIS scope, much less ever played with one. Nor were we ever likely to need to use the knowledges, so this seemed like an enormous redass to no discernable purpose.
I still don't see the point to making One Big NATOPS. I still also don't get why they can't designate new versions in a T/M/S with letters instead of program acronyms, unless it's a way to make big programs sound less-big to Congress. "No, Senator, it's just an equipment upgrade."
I think we once figured up that if they moved the E-2 up a letter every time they made a major change to the plane, we should be on the E-2G or E-2H by now.
